This is great! The goals seem reasonably ambitious and mostly doable over a few years.

I am surprised by #2: "Build a household robot". It's my understanding that efficient actuation and power are largely unsolved problems outside of the software realm. What's the plan for tackling stairs, variable height targets, manipulator dexterity, power supply, etc. in a general purpose robot with off-the-shelf parts? (Answering these questions may be part of that goal but maybe someone knows more on the subject.)
